Since the code is long, let me explain what I am having a problem with, and what I am trying to accomplish first:
I have 3 blocks of php 'WORKING' code that when it's running.
I want it to display some images from mysql db, in a sorted way (order by price) with a text link under the image and when either the image or text link is clicked it creates a new page dynamically based on the id of that item in the db.
I believe I have all the code required for this and I sorted it all out...If you test it locally it will work, up to a point...I get the image -- the text under it, and a link to the id of a new page, the url changes but I want to use an entirely clean window for that link with the new template.
FWIW: The new template will be basically a larger image of the one on the inital page and will contain some details from the db.
Also, the << pagination code >> get's slightly messed up when you enable block 3 of the code, I can't figure it out...You need to try that.
Speaking of the pagination code, how could I limit that code so there is no more than a given amount of images from that script? I currently have the ability to set how many per page, which is good, but if I set more than 5 it will not create a new row, it just keeps putting the images in one row, I would like to have the ability to set a variable to put as many rows as I want.
Code:
DB Fields: (not all are being used in the following script)
Element_1 = Name of website
Element_2 = Website URL
Element_3 = Description
Element_4 = Price
Element_5 = Image URL
(by the way, this is all inside one index.php -- except of course that bit ^^ about the elements above.)
Here's the three blocks of code:
Block 1 - Pagination Code
PHP Code:
<?php
include('config.php'); // DB connect script
// Begin Pagination Code //
$tbl_name="ap_form_1"; //your table name
// How many adjacent pages should be shown on each side?
$adjacents = 1;
/*
First get total number of rows in data table.
If you have a WHERE clause in your query, make sure you mirror it here.
*/
$query = "SELECT COUNT(*) as num FROM $tbl_name";
$total_pages = mysql_fetch_array(mysql_query($query));
$total_pages = $total_pages[num];
/* Setup vars for query. */
$targetpage = "index.php"; //your file name (the name of this file)
$limit = 1; //how many items to show per page
$page = $_GET['page'];
if($page)
$start = ($page - 1) * $limit; //first item to display on this page
else
$start = 0; //if no page var is given, set start to 0
/* Get data. */
$sql = "SELECT * FROM $tbl_name ORDER BY ABS(`element_4`) DESC LIMIT $start, $limit";
$result = mysql_query($sql);
/* Setup page vars for display. */
if ($page == 0) $page = 1; //if no page var is given, default to 1.
$prev = $page - 1; //previous page is page - 1
$next = $page + 1; //next page is page + 1
$lastpage = ceil($total_pages/$limit); //lastpage is = total pages / items per page, rounded up.
$lpm1 = $lastpage - 1; //last page minus 1
/*
Now we apply our rules and draw the pagination object.
We're actually saving the code to a variable in case we want to draw it more than once.
*/
$pagination = "";
if($lastpage > 1)
{
$pagination .= "<div class=\"pagination\">";
//previous button
if ($page > 1)
$pagination.= "<a href=\"$targetpage?page=$prev\"><< previous </a>";
else
$pagination.= "<span class=\"disabled\"><< previous </span>";
//pages
if ($lastpage < 7 + ($adjacents * 2)) //not enough pages to bother breaking it up
{
for ($counter = 1; $counter <= $lastpage; $counter++)
{
if ($counter == $page)
$pagination.= "<span class=\"current\">$counter</span>";
else
$pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>";
}
}
elseif($lastpage > 5 + ($adjacents * 2)) //enough pages to hide some
{
//close to beginning; only hide later pages
if($page < 1 + ($adjacents * 2))
{
for ($counter = 1; $counter < 4 + ($adjacents * 2); $counter++)
{
if ($counter == $page)
$pagination.= "<span class=\"current\">$counter</span>";
else
$pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>";
}
$pagination.= "...";
$pagination.= "<a href=\"$targetpage?page=$lpm1\">$lpm1</a>";
$pagination.= "<a href=\"$targetpage?page=$lastpage\">$lastpage</a>";
}
//in middle; hide some front and some back
elseif($lastpage - ($adjacents * 2) > $page && $page > ($adjacents * 2))
{
$pagination.= "<a href=\"$targetpage?page=1\">1</a>";
$pagination.= "<a href=\"$targetpage?page=2\">2</a>";
$pagination.= "...";
for ($counter = $page - $adjacents; $counter <= $page + $adjacents; $counter++)
{
if ($counter == $page)
$pagination.= "<span class=\"current\">$counter</span>";
else
$pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>";
}
$pagination.= "...";
$pagination.= "<a href=\"$targetpage?page=$lpm1\">$lpm1</a>";
$pagination.= "<a href=\"$targetpage?page=$lastpage\">$lastpage</a>";
}
//close to end; only hide early pages
else
{
$pagination.= "<a href=\"$targetpage?page=1\">1</a>";
$pagination.= "<a href=\"$targetpage?page=2\">2</a>";
$pagination.= "...";
for ($counter = $lastpage - (2 + ($adjacents * 2)); $counter <= $lastpage; $counter++)
{
if ($counter == $page)
$pagination.= "<span class=\"current\">$counter</span>";
else
$pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>";
}
}
}
//next button
if ($page < $counter - 1)
$pagination.= "<a href=\"$targetpage?page=$next\"> next >></a>";
else
$pagination.= "<span class=\"disabled\"> next >></span>";
$pagination.= "</div>\n";
}
// End Pagination Code //
Block 2 - Image Resize Code
PHP Code:
// Begin Resize Image To Specific Dimensions Code //
$dir = "http://www.webmaster-talk.com/images/"; //dir of your images
$exten1 = "jpg"; //extension -> jpg / gif / png
$exten2 = "png"; //extension
$exten3 = "gif"; //extension
$maxwidth = '190'; //maximum width
if ($handle = @opendir($dir))
echo "<table>";
echo "<tr>";
{
while (false !== ($file = @readdir($handle))) {
$bestand = $dir ."/". $file;
$ext = pathinfo($bestand);
if($ext['extension'] == $exten1 || $ext['extension'] == $exten2 || $ext['extension'] == $exten3)
while($row = mysql_fetch_array($result)) {
{
$width = getimagesize($bestand);
if($width[0]<$maxwidth)
{
echo "<td align=\"center\">";
echo "<a href=\"http://localhost/scripts/index.php?id=$row[$id]\"><img src=\"http://www.webmaster-talk.com/images/$row[element_5]\" alt=\"$row[element_1]\" title=\"$row[element_1]\">";
echo "<p />";
echo "<a href=\"$row[element_2]\">$row[element_1]</a>";
}
else
{
echo "<td align=\"center\">";
echo "<a href=\"http://localhost/scripts/index.php?id=$row[id]\"><img src=\"http://www.webmaster-talk.com/images/$row[element_5]\" width='$maxwidth' alt=\"$row[element_1]\" title=\"$row[element_1]\">";
echo "<p />";
echo "<a href=\"$row[element_2]\">$row[element_1]</a>";
}
}
}
}
@closedir($handle);
}
echo "</tr>";
echo "</td>";
echo "</table>";
// End Resize Image To Specific Dimensions Code //
Block 3 - Page generation code (the echo's were used to try test this part of the script)
PHP Code:
// Begin of page generation code //
/*
$id = $_GET['id'];
$query = "select * from $tbl_name where id = '$id'";
$result = mysql_query($query);
$row = mysql_fetch_array($result);
echo "<br />";
echo "Website: ". $row['element_1'];
echo "<br />";
echo "Website Url: ". $row['element_2'];
$query = "select id from $tbl_name";
$result = mysql_query($query);
while($row=mysql_fetch_array($result))
{
echo "<a href=index.php?id=".$row['id'];
}
*/
// End of page generation code //
?>
Code:
<div align="center">
<?=$pagination?></div>
Thanks!
